Patent CA-2381196-A1 (CA)
Title: Vibration compensation for sensors
Inventor: VALLOT LAWRENCE C
IPC: G01C21/16
Filed: 2000-08-04
Abstract: Vibration induced errors in sensors are predicted based on a measurement of vibration power spectra. Accelerometer samples are used to estimate vibration power spectral densities. A calibration procedure using suitable vibration stimulus provides the ability to estimate sensitivity coefficients to be used to compensate for the vibration induced error. High rate vibration measurement samples are provided as input to a power spectral density estimator. The vibration power spectrum estimates are then combined with previously obtained calibration coefficients to generate real time bias correction. Vibration bias sensitivity coefficients are estimated in a controlled environment to ensure their accuracy to compensate the sensor in real-time applications using acceleration measurement devices such as accelerometers mounted to a rigid sensor assembly shared with the sensor to be compensated. Vibration bias estimates are then combined with outputs from both a gyro and accelerometer, which combined from an inertial sensor.

Title: Enhanced three-dimensional container display
Inventor: ZAKSENBERG ISSAC
IPC: B44C5/00
Filed: 2000-09-28
Abstract: The three-dimensional design of a container (20) is enhanced by the suspension of a three-dimensional de-sign (36) within the container. This is accomplished by a de-pending member (34) which is a part of a container closure (26) or which is supported by the upper edge (27) of a container and held in place by a closure (26). This depending member (34) has a three-dimensional design (36) attached thereto or as an integral part thereof. In a further embodiment the liquid in the container (20) and the material of the depending mem-ber (34), and optionally a dip tube (54), have refractive indices whereby the depending member (34) and dip tube (54) sub-stantially visually disappear in the liquid of the container. The result of the foregoing embodiments is a container that has a striking three-dimensional design appearance.

Abstract: Memory resident queues are monitored at predefined time intervals. When the monitoring indicates that a particular queue is not being serviced at a desired level, then action is taken to sweep one or more messages from the queue. The sweeping of the messages frees up system resources associated with the messages, thus allowing other tasks to be serviced. If, after the sweeping, it is determined that the queue can handle additional messages, then one or more messages are placed back on the queue.

Title: Lame de coupe destinee a couper des matieres de feuilles d'emballage
Inventor: FRANK ARMIN
IPC: B65D83/08
Filed: 2000-11-13
Abstract: L'invention concerne un dispositif de coupe destiné à des distributeurs de matière d'emballage en film plastique ou en autres feuilles. Ledit dispositif comprend un élément doté d'une longueur correspondant à la longueur du boîtier de distribution et une section transversale en forme de U conçue pour glisser sur le bord libre du panneau avant du boîtier de distribution. L'élément présente une bande de base dotée d'une branche à l'intérieur du boîtier et d'une seconde branche exposée à l'extérieur de boîtier. Les branches rencontrent la bande dans des épaulements courbés, divergent vers le bas et vers l'extérieur et possèdent des volets d'extension au niveau de leurs extrémités inférieures qui sont courbées vers l'intérieur de l'élément en forme de U de manière à produire des bords de retenue qui se projettent de manière angulaire vers le haut et vers l'intérieur de l'élément en forme de U afin de résister à un déplacement vers le haut de l'élément en partant du panneau. Les proportions des volets courbés vers l'intérieur et la distance entre ceux-ci sont telles qu'il est impossible que la ou les branches d'une lame coupante bloquent la ou les branches d'une autre lame coupante. La distance ouverte entre les volets courbés intérieurement est quelque peu inférieure à l'épaisseur du panneau, et est pratiquement inférieure à la largeur de la bande, de telle manière que la bande d'un élément ne peut pas se bloquer entre les branches des autres éléments. La bande de base de la lame présente une partie médiane plate s'étendant entre les branches et soutenant les dents.

Title: Improved systems and methods for servicing ball valves
Inventor: MULLINS DOUGLAS O
IPC: F16K43/00
Filed: 2002-10-15
Abstract: A temporary ball valve support structure is utilized to apply pressure to the ball in a ball valve so that a seal is maintained between the ball and the upstream seal member in the ball valve to prevent fluid from leaking from the valve while the valve is being serviced. The temporary ball valve support allows a downstream seal member and the ball valve retainer housing assembly to be removed. This allows the outer seal and retainer to be replaced and/or serviced without allowing fluid to escape from the tank or pipe. First and second ball support members are alternately used to force the ball member against the upstream seal member.

Abstract: The present invention relates generally to a method of inducing, promoting or otherwise facilitating a change in the phenotype of an animal cell or group of animal cells including a animal comprising said cells. The modulation of phenotypic expression is conveniently accomplished via genotypic manipulation through such means as reducing translation of transcript to proteinaceous product. The ability to induce, promote or otherwise facilitate the silencing of expressible genetic sequences provides a means for modulating the phenotype in, for example, the medical, veterinary and the animal husbandry industries.  Expressible genetic sequences contemplated by the present invention including not only genes normally resident in a particular animal cell (i.e. indigenous genes) but also genes introduced through recombinant means or through infection by pathogenic agents such as viruses.

Abstract: A valve for a liquid dispensing container includes a body adapted to mount on a liquid container. The body has a cavity with a peripheral sidewall and a flexible resilient bottom diaphragm. A liquid inlet is provided through the sidewall of the body. A valve member is provided having a first end, a second end, and a peripheral sidewall. An outlet extends through the sidewall adjacent the first end.      A flow passage extends through the valve member from the second end to the outlet. The valve member seals the cavity and is reciprocally movable in the cavity between a first retracted position and an extended position. In the first retracted position, the outlet of the valve member is blocked by the sidewall of the body. In the extended position, the outlet of the valve member protrudes out of the cavity, thereby allowing liquid to flow from the inlet along the flow passage to the outlet. The valve member is coupled to the bottom diaphragm. The bottom diaphragm biases the valve member into the first retracted position. The valve member is moved from the first retracted position to the extended position to permit liquid to flow.
